Elitedesk 800 G3 - Additional whitespace added when typing

[Jnthn]

Hello everyone.

Bit of a strange phenomenon that after a bit of differential diagnosis I think is hardware (or possibly driver) related:

My customer reports (and I have confirmed, both on her Elitedesk and mine) that from time to time, with no immediately obvious pattern that when typing, whitespace (one or more spaces, one or more tabs and possibly newline) is being injected into text. I've seen this in the CMD prompt, Notepad, Office 2016 apps and a line of business app used by my customer. 

I've eliminated autocorrect as a cause, and have been working through settings, malware(!) and fully updating firmware and drivers, yet the issue persists. We've even rotated keyboards in case it's hardware.

Any suggestions or known issues?

I think I've got to the bottom of this issue - it's the keyboard itself. Specifically, my customer uses the KBAR211 slimline wired USB keyboard. This morning, on my destkop I noticed that the lightest of touches to the right hand of the space bar started a stream of spaces.  By light touch, I mean resting on the key without any perceptable depression. A few heavier strikes and it hasn't disappeared.

This appears to be either a design- or manufacturing flaw of the model.
